项目历史

Many Tricks developed Key Codes as a free macOS utility for displaying the Unicode value, virtual key code, and modifier state of keyboard input. Version 2.0 brought Retina support, a persistent history view, and direct-edition updates through Sparkle; later releases added modifier breakdowns, Apple-silicon support, dark-mode improvements, and web-hosted help.

采用历史

Many Tricks has offered Key Codes as a free utility both directly and through the Mac App Store. Its narrow focus made it a convenient diagnostic tool for Mac developers and users investigating keyboard events.

使用方式

A user opens the application's single log window and presses keys or key combinations. Key Codes reports the resulting character, key code, and modifiers; optional controls also track key-up events and modifier-state changes.

为什么软件包爱好者会关心

Key Codes is the sort of small, single-purpose macOS diagnostic utility favored by package collectors: it exposes low-level keyboard-event information without requiring a custom test program. Many Tricks also made the source available for developers to inspect.
